I agree with a lot of people here that there's a distinction between doing something significant and being remembered for it. Addressing the latter, though, I think it's kind of a waste of time. Many here are pointing out certain inventions or innovations or constructions or whatever from 1000 years ago that people today appreciate. But I would venture to guess that 1000 years ago those people wouldn't have thought the same of those accomplishments. My point being that people 1000 years from now will value things differently than we do, so it's really impossible to say what "thing" you could do today that people would give a crap about in 1000 years.
